Description

Drying Apparatus {Drying Apparatus}

The present invention relates to a drying apparatus, and more particularly, to a drying apparatus capable of efficiently drying various coatings, printing, leather or agricultural products by improving the structure, and preventing the object from being deformed during drying.

In general, a drying apparatus refers to an apparatus for removing residual moisture by evaporating or mechanically separating moisture contained in an object by heat or hot wind.

The object to be dried may be various coatings or leather products applied to automobiles or general panels, furniture, agricultural products and the like. Here, the agricultural and aquatic products to be dried may include agricultural products such as red pepper, tobacco leaf tobacco, mushrooms, ginseng, rice ginseng, rice, radish, and garlic, and marine products such as seaweed, kelp and anchovy.

Drying apparatus is generally designed to be different in size, capacity, structure, etc. according to the object to be dried. Among them, a hot air drying apparatus for drying an object by hot air is typically manufactured. However, such a conventional hot air drying apparatus has a problem in that a volatile solvent remaining in the drying furnace is exploded due to static electricity or a flame, causing a fire. .

In addition, the hot air drying apparatus has a problem that the heat efficiency is low to heat the fabric for a long time due to the use of hot air, thereby causing a thermal shock to the fabric to degrade the quality. In particular, when drying furniture or leather products, there was also a problem that deformation of the object occurs during the drying process.

In addition, when petroleum or coal is used as a combustion raw material to generate heat required for drying, nitrogen oxides, sulfur oxides, carbon monoxide, etc. are generated, leading to pollution, and there is a safety risk that is harmful to workers.

The present invention is to solve the above problems, the object of the present invention is to provide a drying apparatus that can effectively dry the object by a simple structure.

Another object of the present invention is to provide a drying apparatus that minimizes deformation of an object during drying.

Still another object of the present invention is to provide an eco-friendly drying apparatus which minimizes the generation of substances causing pollution.

In order to achieve the above object, the present invention is a housing provided with a gas supply unit for injection of combustion gas on one side and the receiving space is formed inside, spaced apart from the gas supply unit in the housing at a predetermined interval, a plurality of Disclosed is a drying apparatus including a flat base plate having two communication holes and a size corresponding to the base plate, provided on an upper portion of the base plate, and including one or more fibrous layers made of porous fibers.

Here, the fibrous layer is composed of a plurality of layers, at least one of the plurality of layers can be configured in the form of a noble metal catalyst coated. The noble metal catalyst may include at least one component of platinum (Pt), rhodium (Rh), and palladium (Pd). In addition, the fibrous layer may be composed of ceramic fibers.

On the other hand, the housing may be provided with a preheating heater for preheating the fibrous layer by an external power source. Alternatively, the housing may be provided with an ignition portion for generating a spark by an external power source to combust the combustion gas, and configured to ignite the combustion gas.

Drying apparatus according to the present invention may be configured to include a leak detection unit for detecting the leakage of the combustion gas on the gas supply path to determine the gas leakage to block the gas supply of the gas supply.

In addition, a pressure controller may be provided on the flow path of the gas supply part to control the pressure of the combustion gas supplied into the housing to a predetermined value or more.

In addition, on the flow path of the gas supply unit, a control valve for adjusting the amount of the combustion gas supplied into the housing may be provided.

Drying apparatus according to the present invention having the above configuration has the following effects.

First, the drying apparatus according to the present invention has the advantage that can effectively dry the object. Specifically, there is an advantage that can effectively dry the object by a simple structure. Specifically, by forming a plurality of communication holes in the base plate inside the housing and configured to evenly supply the combustion gas to the catalyst layer through the communication holes, the combustion reaction in the catalyst layer can be made smoothly.

In addition, due to the high penetration of far-infrared heat is transmitted evenly to the interior of the object as well as the surface of the object to enable effective drying.

Second, there is an advantage that can minimize the deformation of the object during the drying process by emitting a large amount of far infrared rays during the combustion reaction. That is, by coating a noble metal catalyst on the fibrous layer, a large amount of far infrared rays are emitted during combustion, thereby minimizing the deformation of the object when the infrared rays are radiated to the object.

Third, since the present invention generates only carbon dioxide and water during combustion, and does not generate any nitrogen oxides, sulfur oxides, carbon monoxide, etc., which are harmful to the human body, various pollutions do not occur, and it is possible to fundamentally prevent the occurrence of harmful elements in the combustion reaction. There is an advantage to that.

Fourth, the drying apparatus according to the present invention has the advantage of minimizing heat loss to the outside, thereby improving energy efficiency.

In particular, the heat loss can be reduced by forming a fibrous layer in the housing in which the receiving space is formed to cause combustion in the housing.

Therefore, like other devices that cause combustion reactions through petroleum or coal, the harmful elements of the human body do not occur, and safety risks can be prevented at the source.

Catalytic combustion such as the present invention generates a large amount of far infrared rays during combustion, thereby preventing the object from being deformed during the drying process. In addition, since it is a direct heating method, there is no heat loss, high energy efficiency, a large amount of negative ions are generated by decomposing moisture generated during combustion, and has an excellent deodorizing and antibacterial effect.

For reference, infrared rays are a kind of electromagnetic waves with a large thermal effect due to a longer wavelength than a red region of visible light. Far infrared rays refer to a long wavelength among infrared rays, and near infrared refers to a short wavelength among infrared rays.

These far infrared rays are invisible, absorbed well by materials, and have strong resonance and resonance effects on organic compound molecules. In addition, since light is generally well reflected when the wavelength is short, and the wavelength is long, the light is well absorbed when reaching the object. Thus, far infrared rays having a long wavelength have a strong penetrating force and thus have an advantage of effectively transferring heat to an object.

In particular, since far infrared rays have a characteristic of heating at the same time not only the surface of an object but also the inside by resonance and resonant action, heat can be uniformly transferred to an object during drying, thereby saving energy by shortening the drying time.
